Scientists at the Vienna Institute of Technology have developed a new technique they call "Photografting", which promises to enable significant advances in bioprinting.

The new technique involves starting with a hydrogel, a porous material in which other molecules can be placed. Lasers then focus on specific spots within the 3D hydrogel and break apart molecular bonds. At these breakpoints new molecules can be easily and rapidly attached. This means one can place specific molecules at specific locations. A bio-designer could then create a model with the right biological structures embedded in the object, a feat not really feasible with today's conventional 3D printing approaches.

Kerry Stevenson, aka "General Fabb" has been writing Fabbaloo posts since he launched the venture in 2007, with an intention to promote and grow the incredible technology of 3D printing across the world. So far, it seems to be working!

Fabbaloo is a daily online publication focusing on the 3D print and additive manufacturing industries. We provide deeper analysis of developments in current and future technologies as well as corporate matters. If there’s something happening in 3D technologies, especially FDM, SLA, SLS and Stereolithography, we’ll have an opinion about it.
